Abstract

Bei einem Verfahren zum Bestimmen des Luftmassenstroms vom Saugrohr in den Zylinder einer Brennkraftmaschine wird der Luftmassenstrom in den Zylinder berechnet, indem vom gemessenen Luftmassenstrom im Saugrohr die Änderungen des gemessenen Saugrohrdrucks, multipliziert mit einem volumen- und temperaturabhängigen Faktor, subtrahiert werden.

Figure 00000001
In a method for determining the air mass flow from the intake manifold into the cylinder of an internal combustion engine, the air mass flow into the cylinder is calculated by subtracting the changes in the measured intake manifold pressure multiplied by a volume-dependent and temperature-dependent factor from the measured air mass flow in the intake manifold.
